Bangladesh is set for a respite from the sweltering heat as a depression over the Bay of Bengal is likely to bring rain across the country, report agencies.
On Friday, a low-pressure system intensified into a deep depression and the resulting squalls triggered a tidal surge around 4 feet above the normal level, according to the Met Office.
A mild heatwave has been sweeping across the country for the last two days, but the rains are expected to bring the mercury down.
In the last 24 hours ending Friday evening, the highest temperature in the country was 37.8 degrees Celsius in Mymensingh. Feni recorded the highest rainfall at 138 mm.
According to the Met Office's 24-hour forecast from Friday evening, the day temperature may drop by as much as 4 degrees Celsius and the night temperature by 2 degrees Celsius across the country.
The maritime ports of Chattogram, Cox's Bazar, Mongla and Payra in Bangladesh have been advised to hoist the local cautionary signal three to alert vessels of a deep depression in the Bay of Bengal.
The depression over the northwest Bay of Bengal and adjoining area has moved west-northwestward and intensified into a deep depression, the Bangladesh Meteorological Department (BMD) said Friday. At 12pm, the depression was centred over northwest Bay and adjoining Bangladesh and India's West Bengal. It is likely to intensify further and move more northwestward.
"Sea will remain rough near the centre of the deep depression. Under its influence, deep convection is taking place over the north Bay and adjoining coastal areas" the weather department said.
Deep convection refers to the thermally driven turbulent mixing that moves air parcels from the lower to the upper atmosphere.
All fishing boats and trawlers in the northern Bay of Bengal and deep sea have been advised to take shelter immediately.
The low-lying areas of Satkhira, Khulna Bagerhat, Jhalokathi, Pirojpur, Barguna, Patuakhali, Bhola, Barishal, Laxmipur, Chandpur, Noakhali, Feni Chattogram, Cox's Bazar and their offshore islands and chars are likely to be inundated by rising tides, BMD said.
